Answer:
The premises that reinforce the thesis statement are A) 1, 2, and 3.
Step-by-step explanation:
A thesis statement consists of one or two sentences with the purpose of informing the reader about the author's opinion and the subject of what will be read, as well as guide the author so that he/she won't lose focus. In the excerpt of Jack London's "The Human Drift", the thesis statement shows us that the idea to be unfolded will concern how man developed better and more precise ways to kill.
Premises are arguments that should reinforce, support the thesis statement. In this case, any premise that proves the evolution of man's killing skills and the variety of man's targets will support the thesis statement well. That is precisely what sentences 1, 2, and 3 do. They mention how man kills to make sure his is the dominant species; how killing devices were invented a little too early in man's history; and how man has developed his skills enough to kill microorganisms.
